Abstract: Objective  To analyze the trend of the registration of patients with new smear-positive pulmonary tuberculosis（NSP）and active pulmonary tuberculosis(AP) nationwide from 2010 to 2012, and to provide reference for the evaluation of case detection.  Methods  The numbers of NSP and AP from the National Tuberculosis Information Management System were used for analysis. The number of population was originated from the National Bureau of Statistics. The annual registration rate of AP and the proportion of NSP in AP were calculated and compared both nationwide and by provinces.  Results  In 2010 and 2012, NSP registered accounted for 46.2% (429 899/931 465)  and 35.4% (316 332/894 199) of AP registered respectively. The registration rates of AP were 69.8/100 000 and 66.4/100 000 respectively in 2010 and 2012, while those of NSP were 32.2/100 000 and 23.5/100 000 respectively. The number of AP decreased by 3.3% from 2010 to 2011 and 1.7% from 2011 to 2012, so did that of NSP (by 12.7% from 2010 to 2011 and 16.5% from 2011 to 2012). The proportions of NSP in AP of 31 provinces ranged from 26.4% to 66.7% in 2010, from 24.1% to 66.3% in 2011,and from 20.7% to 63.1% in 2012.Compared with the data in 2010, 7 provinces had a rise in the yearly registration rate of AP in 2012 with an average annual increase from 0.74% to 6.97%, and 24 provinces had a decline with an average annual decrease from 0.12% to 12.26%. While 30 provinces had a significant decline in the yearly registration rate of NSP with an average annual decrease from 1.38% to 46.33%, and only one province increased by 2.94% annually. Conclusion  There was a slight decline in the registration rate of AP but a significant decline in that of NSP nationwide, especially in some provinces, which is worthy of further investigation.
